Microsoft: Windows 11 update causes Outlook freezes for POP users

A recent Windows 11 security update (KB5074109) is causing classic Outlook to freeze for users with POP email accounts on versions 25H2 and 24H2.

Microsoft is investigating but hasn’t provided a fix yet. The temporary workaround is uninstalling the update through Windows Settings, though this may leave devices vulnerable to security threats. Microsoft will provide updates as they learn more about the issue.​​​​​​​​​​​​​​​​
